The first step is to set up the camera on the tripod. It’s pretty crucial to make sure everything is locked down as any movement could totally ruin the shot. The camera needs to be set on manual exposure, with a moderately low ISO to avoid the amount of digital noise. The aperture should be small enough that you get a suitable depth of field, and the shutter speed should be set to Bulb. You’ll want to manually focus onto the subject. If your lens has vibration reduction or image stabilisation, be sure to switch this off too.
Consider your location and set up
You are going to need to swing your lights so make sure you clear a large enough area in whatever space you are using. Any area where you usually swing cats is probably ideal.
Once you have worked out where you will be creating your orb, mark the central point on the ground so that you have a clear plae to return and rotate your lights around.
Remember to make sure all battery-operated equipment is fully charged beforehand and that the light from your phone or whatever device you have hooked up isn’t going to get in the exposure.
Connect your cable release
Connect your cable release to your camera (we’re using Triggertrap Mobile in this example) and open up Press and Lock mode.
Preparing your lights
The next step is preparing your string of lights so that they are in one defined group. Select a handful of the lights and securely tape around them so they are all facing in the same direction together. Then put tape over the rest of the lights so that they are no longer visible when turned on. You should probably check if there is any unwanted light leaking before you begin photographing.The lovely people at lightpaintingphotoraphy.com have really good instructions with accompanying photographs to help you with this stage.
